ABSTRACT:
Scintillator panel (1) comprises a radiation transmitting substrate (5), which has heat resistance, a dielectric multilayer film mirror (6), as a light reflecting film and is formed on the radiation transmitting substrate (5), and a scintillator (10), disposed on the dielectric multilayer film mirror (6) and emits light by conversion of the radiation (30) that has been made to enter the radiation transmitting substrate (5) and has passed through the dielectric multilayer film mirror (6). Since the radiation transmitting substrate (5) has heat resistance, the dielectric multilayer film mirror (6) can be vapor deposited at a high temperature and, as a result, can be formed in a state of high reflectance. Also, unlike a metal film, the dielectric multilayer film mirror (6) will not corrode upon reacting with the scintillator (10).
